Abstract

A method for forming an insulating film on a grain-oriented silicon steel sheet by applying an insulating coating solution comprising 100 parts by weight (calculated as the solid component) of a mixture of colloidal substances, composed of50 to 98 weight % (calculated as the solid component Sio2) of colloidal silica having a partical diameter not larger than 50 nano m, and 2 to 50 weight %
(calculated as the solid component) of at least one colloidal substance having a particle diameter ranging from 80 to 3000 nano m, selected from the group consisting of oxides, carbides, nitrides, sulfides, borides, hydroxides, silicates, carbonates, borates, sulfates, nitrates and chlorides of Fe, Ca, Ba, Zn, Al, Ni, Sn, Cu, Cr, Cd, Nd, Mn, Mo, Si, Ti, W, Bi, Sr and V; 130 to 250 parts by weight of one or more phosphates of Al, Mg, Ca and Zn; and 10 to 40 parts by weight of chromic anhydride, chromate and/or dichromate. The insulating film that is so produced has a good surface film lubricity, a good heat resistance, an excellent workability for winding into a wound core and an excellent iron loss property.
